General Description
The HMC137 Bi-Phase Modulator is designed to phase-modulate an RF signal into reference and 180 degree states. Device input is at the RF port and output is at the LO port. The polarity of the bias current at the control port (IF port) defi nes the phase states. Excellent amplitude and phase balance provided by closely matched monolithic balun and diode circuits delivers 20 dB of carrier suppression in a tiny monolithic chip.
